Delete a message and optionally timeout the user
AI agents call moderate_message to permanently remove resources in Discord MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Message deletion is a destructive operation that cannot be undone. While timeouts are reversible, the primary function (deletion) and the capability to restrict user access make this high-severity. The tool modifies server state in ways that remove user-generated content permanently and can impact user experience.
From the tool's definition Delete a message and optionally timeout the user — the tool performs irreversible deletion of messages and can impose disciplinary actions (timeout) on users.
Attacks that exploit this kind of access
Delete a message and optionally timeout the user. It is categorised as a Destructive tool in the Discord MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Discord MCP Server MCP server in PolicyLayer and add a rule for moderate_message: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Discord MCP Server. Nothing to install.
moderate_message is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the moderate_message rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for moderate_message. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
moderate_message is provided by the Discord MCP Server MCP server (wowjinxy/mcp-discord). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
